Abstract
We investigated the synergistic effects of co-infection by zucchini yellow mosaic virus (ZYMV) and cucumber mosaic virus (CMV) on viral distribution in the vascular tissues of cucumber. Immunohistochemical observations indicated that ZYMV was present in both the phloem and xylem tissues. ZYMV-RNA was detected in both the xylem wash and guttation fluid of ZYMV-inoculated cucumber. Steam treatment at a stem internode indicated that ZYMV enters the xylem vessels and moves through them but does not cause systemic infection in the plant. CMV distribution in singly infected cucumbers was restricted to phloem tissue. By contrast, CMV was detected in the xylem tissue of cotyledons in plants co-infected with CMV and ZYMV. Although both ZYMV-RNA and CMV-RNA were detected in the xylem wash and upper internodes of steam-treated, co-infected cucumbers grown at 24 °C, neither virus was detected in the upper leaves using an ELISA assay. Genetically modified CMV harboring the ZYMV HC-Pro gene was distributed in the xylem and phloem tissues of singly inoculated cucumber cotyledons. These results indicate that the ZYMV HC-Pro gene facilitates CMV entry into the xylem vessels of co-infected cucumbers.

FIG. S1 Tissue immunoblot analysis of stem sections of cucumber plants inoculated with CMV alone or with CMV and ZYMV. Tissue prints for the detection of CMV at 3, 5, and 7 dpi. The locations of the sections are indicated by lines labeled (a) to (h). The positions of the tested internode sections are indicated on the right. Purple-stained areas show the distribution of CMV CP. Note that at 3 dpi, CMV CP was detected in almost all upper parts (d, e, f, and g) of doubly infected cucumber, while CMV CP was detected only in the stem below the inoculated leaf of singly infected cucumber. Tissue immunoblot analysis was carried out as described by Ryang et al. (2004). The cut surface of the stem was pressed directly onto nitrocellulose membranes (GE Healthcare, WI). The nitrocellulose membranes were incubated with a viral CP-specific primary antibody and an alkaline phosphatase-conjugated IgG and incubated in BCIP/NBT color substrate solution (Sigma, MO).
